We introduce a dual-polarized (DP) Fabry—Pérot cavity (FPC) antenna operating at the millimeter-wave (mmWave) frequency band with high-gain and wideband characteristics. A DP feeding source and a partially reflective surface (PRS) integrated with a Fresnel zone lens are suggested to realize dual-polarization wave radiation over a wide impedance bandwidth. The feeding source provides vertical and horizontal polarizations while keeping high isolation between the two polarizations. PRS is used to realize Fabry cavity to produce a directive beam radiation. The integrated Fresnel zone rings are introduced for phase correction, leading to a significant gain enhancement for the antenna. For verification, a 60-GHz FPC antenna prototype with DP radiation is designed and fabricated with measurement results. It consists of a feeding source, a PRS integrated with a Fresnel zone lens, a quasi-curved reflector, and four three-dimensional printed supporters. The results illustrate that the peak gains of vertical and horizontal polarizations are 18.4 and 17.6 dBi, respectively. The impedance matching bandwidth for the two polarizations is 14%. The performance ensures that the proposed DP FPC antenna is a promising candidate for the fifth-generation wireless communication systems in the mmWave band.

我们介绍了一种双极化（DP）法布里-佩罗腔（FPC）天线，该天线在毫米波（mmWave）频段上工作，具有高增益和宽带特性。建议将DP馈源和与菲涅耳带状透镜集成在一起的部分反射表面（PRS）在较宽的阻抗带宽上实现双偏振波辐射。馈电源提供垂直和水平极化，同时在两个极化之间保持高度隔离。PRS用于实现法布里腔以产生定向光束辐射。引入了集成的菲涅耳波带环以进行相位校正，从而显着提高了天线的增益。为了验证，设计并制造了具有DP辐射的60 GHz FPC天线原型，并提供了测量结果。它由一个喂食源组成，集成了菲涅耳带状透镜，准弯曲反射镜和四个三维印刷支撑物的PRS。结果表明，垂直和水平极化的峰值增益分别为18.4和17.6 dBi。两种极化的阻抗匹配带宽为14％。该性能确保所提出的DP FPC天线是mmWave频段中第五代无线通信系统的有希望的候选者。
